The Necrobinder

When Necrobinder enters, Amass Osty 1. (To amass Osty X, put X +1/+1 counters on an Army you control. It’s also a Legendary Skeleton. If you don’t control an Army, create a 0/0 Legendary black Skeleton Army creature token first.) If you would amass an Army, Zombies or Orcs, instead amass Osty. At the beginning of your upkeep Amass Osty 1. Doom - Whenever an opponent is dealt non-combat damage, they gain that many Doom Counters. (When an opponent’s doom counters are equal to or greater than their life total, they lose the game at the end of their turn).
